💥 Spark: Events as Internal APIs At NDC Oslo, one quote from James Eastham really stuck with me during his talk: “Think about your events as internal APIs.” This simple mindset shift has deep implications for how we design, evolve, and document event-driven systems. Just like internal APIs, events deserve: Clear contracts — schemas, versioning, and well-defined intent Ownership — someone needs to own the lifecycle and semantics Documentation — make it obvious what the event means and when it’s emitted Stability — no breaking changes without coordination This spark reminded me that reliability in event-driven systems isn’t just about infra or retries — it’s about treating your events as first-class citizens in your architecture. ...

Both conda and Python’s built-in venv module are excellent tools for creating virtual environments. ...

Running out of disk space on your Ubuntu server can cause performance issues and prevent applications from running properly. This guide provides straightforward steps to help you check disk space usage and clean up your server effectively. Check Current Disk Space Usage To see how much disk space is currently being used, open your terminal and run: df -h df displays disk space usage. -h makes the output human-readable. This command shows disk usage for all mounted filesystems. Look at the Use% column to identify filesystems with high usage. ...
